Detailed thermodynamic investigation of carbon dioxide capture with amine functionalized mesoporous materials
Abstract/Contents
- Abstract
- The work in this doctoral dissertation is divided into two parts. First, the synthesis and characterization of oxidized metal-salen complexes as models for galactose oxidase, a metalloenzyme that relies on ligand redox "non-innocence" for its activity, is explored. It is shown that simple changes to the salen ligand structure can dramatically affect the locus of oxidation with a variety of metal centers. A series of one- and two-electron oxidized copper(II)-salen complexes are characterized using a variety of spectroscopic, electrochemical, and theoretical methods. The second part of this dissertation explores the use of amine-functionalized mesoporous materials for carbon dioxide capture. We have investigated the thermodynamics and kinetics of carbon dioxide adsorption/desorption reactions for a series of diamine-functionalized SBA-15 materials. Enthalpic and entropic contributions to the free energy of carbon dioxide adsorption/desorption are correlated to the structure and surface distribution of sorbent molecules. Additionally, a novel and highly reproducible method for the bromomethylation of mesoporous carbon materials is reported. Bromomethylated materials can be derivatized further by a variety of methods to yield novel functional materials. Specifically, carbon materials functionalized further with diamines are capable of carbon dioxide capture by a process similar to that observed for diamine-functionalized SBA-15 materials.
